As I previously wrote I bought from e-bay an "Oric Atmos 48k pour récup".
It didn't work but this was expected. I started to desolder the bigger chips and to test them - all chips are OK!
So I decided to continue the torture (not sure who was the victim me or the motherboard ) and removed everything!
Here is the result:

My first goal is accomplished: to take HiRes pictures of the empty board.
I scanned it with 1200 dpi and now I have both sides in 2x200 MB files (Windows BMP format).
Linear dimensions are preserved, so pictures can be used as template or for reference.
I think it would be helpful to place them somewhere in public (ideas?)

Next I'll re-solder everything back, replacing some ugly looking parts with shiny new components.
Second goal is: to have a "boutique" Oric Atmos (optionally working )

Desoldering was made in "old fashion" way - using usual soldering iron and vacuum pump.
Actually the board quality is surprisingly good! I was bit worried about the thin tracks but they endure well the heat.
Else from one moment the task becomes boring but helps for calming down the stress and meditation .

They should be accessible for everyone (i.e. even without google account). Both files with preview are the JPG's from my fist post,
the other 2 (without preview) are the ~200MB pictures.

The PCB are quite good quality expect for the soldermask which just crack overtime, but this is a common issue on 80's PCB.

Neat job. I have a lot of trouble desoldering neatly. I've just ordered a new soldering iron. Maybe a need a new noozle for my solder sucker?
I find the copper track can lift off. I tried desoldering braid but that made a mess of the board and didn't suck up the solder very well.
